AJAX: A Comprehensive Guide to Sending and Receiving Data
Sending JSON Data to the Server
To send a JSON encoded string to the server using jQuery, follow these steps:
1. Use the JSONstringify Method
Pass your JavaScript object through the JSON.stringify method to convert it into a JSON string.
const data = JSON.stringify(myObject); 2. Pass the JSON String as the Data Parameter
In the data parameter of the jQuery ajax function, pass the JSON string.
$.ajax({ url: "submit.php", type: "POST", data: data, }); Handling AJAX POST Requests in PHP
To handle AJAX POST requests in PHP:
1. Create a PHP File to Receive Data
Create a PHP file, such as getDataphp, to retrieve the data from the incoming request.
2. Retrieve Values from the _POST Array
In the PHP file, you can access the data sent via the POST request from the _POST superglobal.
$data = $_POST['data'];
